1. An appliance for heat treatment or inductive heating or cooling of shrink chucks for shaft-shaped tools or a shrinkage appliance or a cooling appliance or a shrinkage appliance with a cooling appliance, the appliance comprising:
a receiving device or a receiving opening for receiving the shrink chuck;
a heat treatment unit or an induction coil arrangement or a cooling unit surrounding said receiving device relative to a central axis; and
a measuring unit for contactless temperature measurement of the shrink chuck;
said measuring unit having a plurality of sensors disposed around said receiving device, said plurality of sensors including at least one first sensor being a temperature sensor for contactless detection of a shell temperature of the shrink chuck disposed in said receiving device, and at least one second sensor being a sensor of a type different than said first sensor for detection of another property of the shrink chuck disposed in said receiving device, said sensors being disposed in at least one of circular form or at different axial heights relative to said central axis at or around said receiving device.
